Did you adjust the GC to check the shared libraries' data sections for 
references? When we looked at this for LDC that turned out to slow down GC 
runs significantly.

I'm pretty sure bearophile benchmarked it at the time.

As far as I remember the main problem was that we were scanning all data 
sections - even of plain C libraries.
